This repair can be applied to ANY electrical connection including, but not limited to: lighting, body electrical, in-line connections, powertrain controlsensors, etc. DO NOT over apply lubricant to the point where it prevents the full engagement of sealed connectors. A light coating on the terminalsurfaces is sufficient to correct the condition.

The technician may determine that he is unable to duplicate the intermittent condition.

Cause

This condition may be caused by a buildup of nonconductive insulating oxidized debris known as fretting corrosion, occurring between two electricalcontact surfaces of the connection or connector. This may be caused by any of the following conditions:

-

Vibration

-

Thermal cycling

-

Poor connection/terminal retention

-

Micro motion

-

A connector, component or wiring harness not properly secured resulting in movement

On low current signal circuits this condition may cause high resistance, resulting in intermittent connections.

On high current power circuits this condition may cause permanent increases in the resistance and may cause a device to become inoperative.

Representative List of Control Modules and Components

The following is only a representative list of control modules and components that may be affected by this connection or connector condition and DOESNOT include every possible module or component for every vehicle.
